Master the ARRT Sonography registry with focused, physics-to-procedure prep.
The ARRT Sonography credential certifies that a technologist has the knowledge and skills to perform diagnostic medical sonography safely and competently. It is administered by the American Registry of Radiologic Technologists (ARRT). Note that the American Registry for Diagnostic Medical Sonography (ARDMS) is a separate, related certifying board that also credentials sonographers; many employers accept either, and the two organizations maintain distinct exams and eligibility routes.
Certification confirms competency across patient care, ultrasound physics and image production, and hands-on scanning procedures spanning the abdomen, obstetrics and gynecology, and superficial structures. The exam is a computer-based, multiple-choice test built from ARRT's published content specifications, blending safety and ethics with instrumentation knowledge and protocol execution.
ARRT offers Sonography through both a primary pathway (for candidates completing an approved educational program as their first credential) and a post-primary pathway (for technologists who already hold an ARRT credential and add Sonography through documented clinical experience). Eligibility requirements and current exam details differ between the two routes, so candidates should confirm their pathway with ARRT.
Mapped to the ARRT content outline.
Ethics, legal practice, communication, patient interaction, and safety workflows before and during exams.
Sound properties, wave interaction with tissue, propagation, attenuation, and the physics underlying image formation.
Transducers, system controls, optimization, Doppler principles, artifacts, and image-quality decision-making.
Sonographic evaluation of abdominal organs, small parts, and superficial anatomy including thyroid, breast, and scrotum.
First-, second-, and third-trimester scanning, fetal anatomy and biometry, and maternal assessment.
Sonographic evaluation of the female pelvis, uterus, ovaries, and adnexal structures.
Scanning protocols, measurements, and documentation across abdominal, OB/GYN, and superficial-structure studies.
Diagnostic medical sonography students completing an accredited program, as well as credentialed radiologic technologists seeking to add sonography through the ARRT post-primary pathway.
Eligibility differs by pathway (primary vs. post-primary) and includes education, clinical competency, and ethics requirements. Requirements change over time; always confirm current details at arrt.org.
